I have a question regarding deletion of partitions on a Mac. Due to some performance issues, I decided to start fresh and created a new partition (NewOSX) on the hard drive, to which I have transferred all the data that I need from my old, original partition (MacintoshHD) along with installing an operating system, downloading apps, etc. I would now like to go ahead and delete the old partition and merge the disk space into my new setup. I know this isn’t as simple as deleting the newer partition would be, as the minus sign in the disk utility partition menu is greyed out.
Here is the info of the two partitions that I am referring to:
Macintosh HD Capacity: 119.2 GB Used: 47.54 GB Device: disk0s2 NewOSX Capacity: 129.35 GB Used: 34.69 GB Device: disk0s4
I am wondering if there is (hopefully) a less than super-technical workaround that can accomplish this task. Thank you.
Note: Though there is 47 GB still on the old partition (MacintoshHD), I no longer need anything from it and it is ready to be wiped clean. Also, both partitions are running the “El Capitan” operating system.

After having some trouble with Internet Recovery Mode and seeing my system crash a few times during reboot, I decided I didn't want to take any risks and mess around with Recovery HDs at all. What I ended up doing was wiping Macintosh HD clean, reinstalling the operating system, and then took a few hours to manually transfer data, redo settings, etc., from NewOSX to Macintosh HD. Then went to disk utility and deleted the NewOSX partition, which of course is a simple procedure. Thanks for the assistance, wish I had realized the simple solution earlier.
